This blog is offered by C-LIGHT as a solution for 100G point-to-point transmission covering 140 kilometers.
C-LIGHT adopts a self-made 100G QSFP28 XZR4 100km optical transceiver and adds an SOA amplifier at a distance of 80KM from point A, providing a total link budget of 47dB and achieving 100G P2P 140KM datacom from point A to point B.
In this solution, the 100G QSFP28 100km XZR4 transceiver of C-LIGHT can provide a transmit optical power of over +4dBm per channel and ensure a sensitivity of -29dBm per channel. The link budget for each channel is greater than 33dB. Combined with a 15dB gain SOA, this solution can provide a total link budget of over 48dB per channel.
Here are link loss and link budget data for each part of the program for your reference.
Now let's see how well this program is implemented.
C-LIGHT chose Nokia 7250 and HW 8000 series switches to verify the effectiveness of this solution
You can see the Nokia 7250 switch link up
And the HW 8000 series switch link up
Receive and transmit power on both switches is within normal limits.
